The first episode of the third season of “Demon Slayer: Kimetsu no Yaiba” was released on April 9, alongside the debut of a new opening theme song. However, there has been some controversy regarding the appropriateness of this new song’s content in relation to the storyline of the third season, leading to numerous criticisms on social media.

The content of “Demon Slayer: Kimetsu no Yaiba” season 3 will focus on the Swordsmith Village arc. In the Swordsmith Village, Tanjiro encounters Love Hashira Mitsuri Kanroji and Mist Hashira Tokitou Muichirou. The group participates in training while searching for a legendary swordsmith.
After the defeat of Upper Moon Six, Muzan sends two other demons to gather information. The special blood demon arts they possess have led them to the Swordsmith Village, where they plan to launch an attack. Tanjiro’s group must confront Upper Moon Four Hantengu, a demon capable of splitting into multiple bodies to fight, and Upper Moon Five Gyokko, a demon that uses art to create deadly “artistic masterpieces.”

The new opening theme song for “Demon Slayer: Kimetsu no Yaiba” season 3 is titled “Kizuna no Kiseki,” performed by the rock band MAN WITH A MISSION featuring vocalist Milet. This powerful and catchy song has sparked considerable debate online, with comments such as: “I don’t really like this new song,” “LiSA and Aimer were much better, I don’t understand why the change,” “I want to like this song but honestly, I’m bored,” “The song doesn’t fit with Demon Slayer at all,” “If it were a sports anime, it might be more fitting.”
“Demon Slayer: Kimetsu no Yaiba” is a widely popular franchise that has significantly impacted the careers of its artists. However, there are concerns regarding the quality of songs that may be overlooked simply because they appear in “Demon Slayer.” The reality, however, is not as straightforward as many might think.
Furthermore, the viewership rating for the first episode of this third season is 8% in the Kanto region. During peak times, some episodes of “Demon Slayer” have surpassed 10% viewership and even approached 20%. Nonetheless, there seems to be a growing concern regarding the decreasing popularity of this once-thriving series, with fewer viewers showing interest compared to when thousands tuned in to watch the show during its initial airing.
